I only have one email and I like it that way. Back a year ago I have set my profile picture to my real photo. Randy dandy do. Until I used Facebook to login to a site that had Gravatar built in. Facebook gave up my email and I instanly had my photo on there. Which I didn't want, but there was no way to change that cause they only had Gravatar to start with. So I had to change my picture to this iOS 7 styled poo (thank you very much).

And then I though, why the hell hassle in the first place? All this Gravatar tracking my website data over a tiny feature to have a single pic everywhere? (which is not always a good thing) Oh, excuse me. Did I say everywhere? I meant somewhere. Because in reality you might have some accounts that support Gravatar and some don't. And you still have to upload a pic. In my UX the latter is the case most of the time and that just defeats the sole purpose of Gravatar.
